<br />SOILS ANALYSIS:
<br />A representative soil sample was taken at the site
<br />and a complete soils analysis conducted by an
<br />independent soils testing laboratory. The texture of
<br />the soils on this site was determined to be a loam.
<br />Values for N, P, and K were 20 ppm, 30 ppm, and 266
<br />ppm, respectively, The complete analysis is available
<br />on request.
<br />The nutrient values reported in this analysis will
<br />provide a basis from which to make fertilization
<br />I recommendations for this site during reclamation.
<br />WILDLIFE ANALYSIS
<br />i A. INTRODUCTION:
<br />The Brannan Sand & Gravel Company has developed
<br />a proposal to mine gravel from a site located south of
<br />132nd and Nome Streets in Adams County. This tract
<br />of approximately 145.5 acres was investigated
<br />during May and June, 1980 to evaluate habitat
<br />conditions and the presence of wildlife on the site.
<br />The property was also inspected with Chuck Grand
<br />Pre, Environmental Resources, Colorado Division of
<br />Wildlife, on 2- 21 -80.

<br />B. MAMMALIAN OBSERVATIONS:
<br />This site is presently being farmed for corn in the
<br />northern portion of the property and alfalfa in the ;' l
<br />southern portion. Several very large cottonwopd 1
<br />trees are distributed along the fence rows and in
<br />some of the fields. A number of irrigation ditches
<br />which carry water from the Fulton Ditch on the south
<br />edge of the property are distributed through the
<br />fields. The ditch edges support a divans ettoeiation
<br />of mixed forbs and grasses in contrast to the
<br />undiversified crop area. A few clumps of various
<br />shrubs occur along the fenced boundaries of the
<br />property.
<br />Field observations conducted through July, 1980
<br />indicated the occasional presence of rabbits, coyotes,
<br />fox, deer, and numerous small rodents. The west
<br />central portion of the property, a pasture between the
<br />cornfield and alfalfa field, her been invaded by prairie
<br />dogs and their colony now covers approximately
<br />twenty -two acres.
<br />A latilog study of the appropriate habitats for this site
<br />was run by the Colorado Division of Wildlife and
<br />indicated that a variety of small mammals and a few
<br />larger species could be expected in this area. A list of
<br />probable species has been developed end no
<br />evidence of any endangered or threatened species
<br />was noted during this investigation.
<br />C. AVIAN OBSERVATIONS:
<br />A variety of birds were noted on the property,
<br />primarily because of the mixed environments that are
<br />available.
<br />Habitat diversity is provided on this site by the
<br />combination of cropland interspersed with heavily
<br />vegetated irrigation ditches, weeds along the fence
<br />rows, clusters of shrubs along the fences, and
<br />approximately 20 large cottonwoods disported on
<br />the property. Additionally, on the southwest pert of
<br />the property an abandoned gravel excavation now
<br />filled with water and invaded by cattails provides a
